# LSR Silicone Lens for Smart Lighting
Manufactured by 橡楚(湖北)橡胶有限公司

LSR Silicone Lens for Smart Lighting is a precision-molded optical component produced from high-purity injection-molded liquid silicone rubber (LSR) by 橡楚(湖北)橡胶有限公司, located at 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号. Designed to meet the growing demand for high-performance optical components in connected and human-centric smart lighting systems, our LSR silicone lenses deliver consistent light transmission, durable mechanical performance, and reliable long-term optical stability for a wide range of residential, commercial, and industrial smart lighting applications.
Unlike traditional glass or polycarbonate (PC) lenses, LSR silicone lenses offer unique advantages for modern smart lighting designs: their inherent softness enables seamless integration with curved or irregular light source layouts, their wide operating temperature range maintains consistent performance in both indoor and outdoor environments, and their low yellowing resistance preserves optical clarity for the full lifespan of the lighting fixture. Our lenses are manufactured using closed-mold precision injection molding, which ensures tight dimensional tolerances and consistent optical performance across mass production runs, making them suitable for both low-volume custom design projects and high-volume OEM smart lighting production.
Every LSR silicone lens we produce is manufactured under controlled production conditions, with in-line quality checks at every stage from raw material compounding to final finishing, to ensure that each component meets the strict optical and mechanical requirements of smart lighting systems.
Our LSR silicone lenses are produced from medical-grade high-purity addition-cure liquid silicone rubber, with no residual low-molecular-weight siloxanes that can cause fogging or contamination of LED chips. Key material properties are listed below:
: Haze | ≤1.0% | ASTM D1003 |
Our LSR silicone lenses are produced via precision cold runner injection molding, with the following standard process parameters to ensure consistent quality:
Unlike PC and PMMA lenses that often yellow after 2–3 years of continuous exposure to LED heat and UV radiation, our addition-cured LSR material retains >98% of its original light transmittance after 5000 hours of accelerated aging testing at 150°C. This prevents light output degradation and color shift, which is critical for smart lighting systems that require consistent color temperature control for human-centric lighting applications.
LSR’s excellent flowability during injection molding allows us to produce complex lens geometries—including thin-walled lenses, multi-faceted freeform lenses, and integrated lens arrays—that are difficult or impossible to achieve with glass or rigid thermoplastics. The inherent softness of LSR also enables press-fit installation without gasketing, simplifies assembly, and reduces the risk of cracking during fixture installation or impact.
LSR silicone has higher thermal conductivity than most thermoplastic optical materials, which helps dissipate heat from high-power LED chips more effectively than PC or PMMA lenses. This reduces operating temperatures of LED chips, extending the lifespan of the entire smart lighting fixture and maintaining consistent light output over time.
Our raw LSR materials are RoHS and REACH compliant, free of lead, cadmium, and other restricted hazardous substances. The non-toxic, inert nature of LSR also makes our lenses suitable for smart lighting installations in residential, healthcare, and educational environments where low-VOC emissions are required.
For high-volume OEM orders, our precision injection molding process delivers shorter cycle times and lower per-unit production costs than precision glass molding, while still meeting tight optical and dimensional requirements.
Our LSR Silicone Lenses for Smart Lighting are designed for a wide range of modern connected lighting applications, including:
We can also produce custom-sized and custom-shaped LSR silicone lenses to meet unique design requirements for specialized smart lighting projects.
Hardness is selected based on the installation method and required mechanical rigidity:
We offer a range of standard lens diameters for common smart lighting applications, including 25 mm, 35 mm, 50 mm, 75 mm, and 100 mm, with a range of standard focal lengths and beam angles (15°, 24°, 36°, 60°, 90°, and 120°) available for quick delivery. Custom sizes, geometries, and optical designs are available for OEM projects with minimum order quantities.
We offer two standard material grades to meet different application requirements:
At 橡楚(湖北)橡胶有限公司, we maintain a strict quality management system certified to ISO 9001, with quality control checks implemented at every stage of production:
We can provide material test reports (MTR) and performance test data with every order to confirm compliance with customer specifications.
